There is no way to fit all of the complex processes onto one A4 page, but I wanted to illustrate an overview that shows how these fit together. The electron transport chain got a bit more complex than I intended to. I guess I’m so very used to drawing this on exams, so I didn’t think about it before it was done. But then I though, hey, that is where most of the energy is produced, so why not.

If you want to learn more about the different processes, I would suggest looking here:
